Vanguard

Vanguards often have a
background as soldiers, elite guards, or otherwise as parts of an
organized fighting unit on the battlefield. Their skill set helps
them charge in and break enemy fortified positions, as well as being
able to hunker down and hold positions of their own. They know how to
fight in ranks effectively, and can help protect their allies.

The vanguard is an expert at making
attacking difficult for his enemies. This grants a Tactical bonus to
melee AC to himself and all allies within reach. If
the vanguard elects to use this stance, the effects last from the
start of his current turn, until the start of his next turn (1 full
round).

The vanguard may use this stance to focus on a more offensive strategy.
Instead of gaining a Tactical bonus to AC, this applies instead to
the vanguard's to-hit and damage rolls. Note that this bonus also
extend to allies. If the vanguard elects to use this stance, the
effects last from the start of his current turn, until the start of
his next turn (1 full round).
